02 — Technology

The membrane is the
whole argument.

Everything we build hangs off one thing: a multi-purpose nano-sieving membrane that we developed ourselves. Everything around it exists to protect that element, keep it clean, and keep it working.

01Principle

Separation, not straining.

A conventional filter pushes contaminated fluid through a screen and keeps what it catches. A membrane separates at the molecular scale: what passes is a different fluid, not merely a clearer version of the same one.

Nano-sieving membrane module — process schematic Contaminated feed enters the housing and passes the nano-sieving membrane element. Contaminants are retained and leave as concentrate; refined fluid leaves as permeate.

A

Feed

Oil or process fluid drawn from the sump, tank or line. Pre-filtered, then brought to the working temperature so viscosity does not quietly set the throughput.

B

Element

The nano-sieving membrane, held between a porous support and a back plate. This is the only place where separation happens.

C

Permeate

Refined fluid, free of the retained fraction and ready to return to service or to be re-blended.

D

Concentrate

The retained stream — water, acids, wear metal, degraded additives. Collected for disposal or for recovery.

02Processes

Four processes that all run
in the same housing.

Combining them in one circuit is what makes the consumable cost of a Fengming Huanyu line close to zero, and the turnaround close to nothing.

01

Graphene nano-sieving

Separation down to 50 and 100 nm across a graphene-based membrane element. This is the process that sets the cleanliness grade of the returned oil, and the reason the system can regenerate rather than replace.

02

Particle-sieving decolourisation

Removes the dark oxidation products that never show up on a particle counter but end up as a thick, tarry filter cake. Colours the fluid back towards new.

03

Screen regeneration

Restores the element's working capacity without swapping media. Over a duty cycle, the media cost per litre of treated oil approaches zero.

04

Electrostatic purification

Charges and captures the fine fraction that resists mechanical sieving. No heat, no chemistry, no solvent — useful on fluids where additives must be preserved.

Verified by a provincial professional institute as filling a gap in domestic technology, with overall performance assessed at international advanced level. Related national projects currently under way cover new membrane materials and oil-sludge treatment technology.

03Recovery

Recovery and regeneration.

The same equipment that cleans oil cleans water, and the same membrane that regenerates a lubricant will polish an effluent stream.

01

Oil regeneration

Used lubricating oil is dewatered, filtered and decolourised back toward base-oil specification, then re-blended or returned to service in place.

02

Sludge reduction

The concentrate stream is dewatered into a drier cake, cutting the volume and the handling cost of what has to leave the site.

03

Water treatment

The same membrane elements polish oily wastewater, produced water and process effluent — including colour and dissolved hydrocarbon.

04

Marine response

A provincial research project covers emergency treatment of marine oil spills; the same hardware adapts to containment and recovery duty.

04 — Research base

More than 10 % of the company is research.

A team led by foreign academician-level experts and established domestic specialists, working with five university partners. Two national and three provincial projects currently under way, more than forty patents.
